So here is the deal: Spring break is coming up and I plan to do a skeletal reconstruction, so I thought I'd try something fun and let you, my loyal readers, choose which animal I'll restore. I've created a list of taxa for which I already have the data (and in some cases began scaling and preliminary work) to choose from.

Late last year Europe got a brand-spankin' new ankylosaur, Europelta carbonensis. It's the most complete ankylosaur yet known from Europe (unless you consider Scelidosaurus to be a basal ankylosaur rather than a basal armored dinosaur). Let's take a look at the anatomy of Europelta, with an emphasis on what we know (and aren't so sure of) when it comes to reconstructing its armor.

Let's start out 2014 right, with a bunch of new and overhauled sauropod skeletal reconstructions. All of the reconstructions of your favorite four-legged dinosaur behemoths (and some of their smallish ancestors) have been brought up to date. For more on this and a look at some of the anatomical changes that have been incorporated into this overhaul click beyond the fold to check it out.

This was an exciting week for tyrannosaur fans, as a new tyrannosaurine was named (Lythronax) and new fossils of Teratophoneus were revealed. Eagle-eyed visitors to the Skeletal Drawing theropod gallery probably realize that they've seen two of these skeletals before, but it may not be the two you would expect.

For those of you wondering why the pace of content has slowed down, it's because I entered a PhD program in paleontology at the University of Wisconsin-Madison this fall, and I lost what was left of my free time. But that's not to say that there hasn't been substantial work going on behind the scenes of SkeletalDrawing.com!

First and foremost, there is a new skeletal gallery featuring some of my non-dinosaur reconstructions. "Non-dinosaurs" is admittedly a pretty broad category, and indeed it features everything from the proto-dinosaur Silesaurusto crocodylomorphs, turtles, mammals, and even the basal tetrapod Ichthyostega.

I have good news and bad news - the bad news is today is not the day you get a general estimate of the mass of Spinosaurus. I know, I know, and I'm sorry. Here's the good news - in preparation for a deeper look at the challenges of estimating the mass of Spinosaurus, I've produced far more rigorous mass estimates of Tyrannosaurus and Giganotosaurus from GDI, and I got some surprising results. Jump below the fold to see who is bigger (and why I think this is so).
